Dark Brahma?

My friend bought this roo and several other chickens from a gentleman that used to show and was selling off his stock. She was told he was a Dark Brahma. In trying to get hens to go with him, she noted that all the Dark Brahma pics are silver over black. This gorgeous guy is goldtoned. She and I have scoured pics and he seems to be Brahma other than his coloring. Any help for her is greatly appreciated.
